simply when your single GPU is not enough, you put another one to add some more power, that same goes for 3 gpus and 4 gpus.
4870x2 vs. GTX280.
that will be how its played. ATI can't come up with a single stronger gpu to face nvidia so they basically slapped on 2 vs. 1 good or bad? we'll see.
However GTX 280 can also SLI/tiple SLI so its HD 4870x2 Crossfire vs. GTX 280 4 vs.2
The scaling with the 4th GPU on 9800GX2 SLI was worst than scaling with 3. thats probably why Nvidia is abandoning it and trying to in prove 3 gpu scaling. ATI needs all the GPUs they can get on a single platform to compete with Nvidia high end performance wise. scaling on ATI's architecture on the 3 and 4th GPU ain't too bad. Come down which games like which videocard and how well ATI and Nvidia can optimize their drivers.
